May is coming in fast, and Acorn TV has announced their first annual Murder Mystery May – a lineup of new and classic mysteries coming to the platform all month long (perhaps scheduled for May because “Murder Mystery July” just doesn't have the same ring to it). Below, we take a look at what's coming. As always, we start with those shows that are continuing in May after premiering in previous months, then follow with the shows premiering in May. This month, there's also an extra section with mystery films coming to Acorn TV in May.

Fair warning: If you already subscribe to AMC+ or Sundance Now, you may not find this month's lineup to be especially satisfying – since many of the “new” shows and films have been available on one or both of those services for a while now.

Shows Continuing on Acorn TV in May 2025

In the new season, the stationhouse welcomes Albert Choi (Paul Sun-Hyung, The Mandalorian, Avatar: The Last Airbender, Kim’s Convenience), a respected and good-humored addition to the team.

Brokenwood Mysteries, Season 11

As they dig into local cases, Shepherd soon realizes that Brokenwood’s peaceful facade hides plenty of secrets and intrigue.
